Abstract (en)
[origin: WO2020099729A1] The invention concerns a method for depositing a functional mineral layer or stack on a glass substrate, comprising the steps of depositing, on the substrate, a photosensitive laser-crosslinkable organic liquid resin composition, crosslinking the resin in a localised manner by means of a laser, eliminating the non-crosslinked liquid composition, depositing, on the coated substrate, a functional mineral layer or stack, then combusting the crosslinked solid resin by means of a heat treatment, completing its elimination and that of the mineral layer or stack by mechanical action, so as to obtain the mineral layer or stack in a pattern corresponding to the negative of that produced with the crosslinked solid resin; also disclosed is an intermediate product of this method and the application of the glazing obtained by this method to allow the passage of radiofrequencies.
